AMOS D. THOMAS, OF MT. ETNA, IOWA, ASSIGNOR OF ONE-HALF HIS RIGHT TO W. D. THOMPSON.

IMPROVEMENT IN SEPARATOR-SHOES FOR THRASHING-MACHINES.

Specification forming part of Letters Patent No. I 68,939., dated October 19, 1875; application filed March 27, 1875.

To all whom it may concern:

Be it known that I. AMOS D. THOMAS, of Mount Etna, in the county of Adams and State of Iowa, have invented a new and useful Improvement in Separator-Shoes for Thrashing- Macl1ines,which improvement is fully set forth in the following specification, reference being had to the accompanying drawings,in which- Figurelis a longitudinal section of the sieve. Fig. 2 is a longitudinal section of a portion of the elevator, showing its arrangement with re- 'spect to the shoe; and Fig. 3, a transverse section of the elevator and of so much of the shoe eign matters likely to clog or choke the elevator, while the wheat passes through said screen or riddle into the bottom of the spout, and thence into the elevator.

A is the spout at the tail of shoe D, discharging into the elevator B, as shown in Fig. 3. O is the screen, placed in the spout so as to leave space between itself and the bottom of the spout for the escape of the grain into the elevator, and projecting through and beyond the elevator-case, as shown.

By this arrangement the Wheat is freed from the large foreign matters before it falls into the elevator.

I claim as my invention- The discharge-spout A, delivering into the elevator B, and provided with a screen or riddle passing through and beyond the casing of the elevator, and over the elevator, substantially as and for the purpose set forth.
